Looking for strain advice

I live in Arizona and I am going to be growing outdoors in 5 gallon containers with an all organic feeding program. We get ton's of sun here and it gets quite hot so I am wondering what strains prefer this type of climate?? What about ATF or matanuska? I love both indica's and sativas so I don't have a preference. My wall is 7feet tall so I don't plan on letting the plants get over 5 1/2 -6 feet tall. Maybe 3 or 4 plants
